To celebrate the upcoming publication of Ben Aaronovitch‘s highly-anticipated ninth Rivers of London novel, AMONGST OUR WEAPONS, Orion Books is running a pre-order competition!

As you can see from the above graphic, anyone in the UK who pre-orders the novel (in any format — print, eBook, audio) can upload proof of purchase and have a chance to win one of 100 exclusive AMONGST OUR WEAPONS coins!

The novel is due to be published in the UK on April 7th. Here’s the synopsis…

There is a world hidden underneath this great city…

The London Silver Vaults – for well over a century, the largest collection of silver for sale in the world. It has more locks than the Bank of England and more cameras than a celebrity punch-up.

Not somewhere you can murder someone and vanish without a trace – only that’s what happened.

The disappearing act, the reports of a blinding flash of light and memory loss amongst the witnesses all make this a case for Detective Constable Peter Grant and the Special Assessment Unit.

Alongside their boss DCI Thomas Nightingale, the SAU find themselves embroiled in a mystery that encompasses London’s tangled history, foreign lands and, most terrifying of all, the North!

And Peter must solve this case soon because back home his partner Beverley is expecting twins any day now. But what he doesn’t know is that he’s about to encounter something – and somebody – that nobody ever expects…

Effortlessly original, endlessly inventive and hugely entertaining – step into the world of the much-loved, Number One bestselling Rivers of London series.

Also, don’t forget that Ben is going to be embarking on a UK book tour, starting April 4th. Full details can be found here.
